. as Will enable others skilled in the art to which it appertains to make and use the same.

lily invention relates to improvements in that class of hydraulic motors which are def signed to be placed in a running stream and be driven by the current thereof 3 and it has for one of its objects to provide such a motor embodying a longitudinal central Water Wheel or screw and means whereby a large volume oi the current may be concentrated in said channel so as to enable it in its passage through the motor to exert great pressure against the blades of the screw or wheel and thereby forcibly and rapidly rota-te the same.

Another object of the invention is to pro vide a hydraulic motor embodying means whereby it may be readily submerged so as to present the Wheel or screw to the full force of the current and means whereby it may be readily raised when it is desired to change its location; and still another object is to provide a hydraulic motor embodying means whereby the entrance to the channel in which the screwwheel is placed may be readily closed, so as to permit of the motor being stopped when desired.

Other objects and advantages of the invention will be fully understood from the follow ing description and claims when taken in conjunction With the accompanying drawings, in which Figure 1 is plan view of my improved motor. Fig. 2 is a vertical longitudinal central section with parts in elevation. F.ig. 3 is a transverse section taken in the plane indicated by the line at :tof Fig. l. Fig. d is a detail side elevation, partly inA section, of the upstream end of the motor. Fig. 5 is a plan view of one of the rotary Water elevators or pumps. Fi g. G is aplan view of the main frame or body of one of the water elevators or pumps. Fig. 7 is a. section taken in the plane indicated by the line .rfc of Fig. 5. Fig. 8 is a section taken in the planeindicated by the line y fy of Fig. 5,

and Fig. 9 is a perspective vienv of one of the scoops or spoons of the Water-elevators removed.

In the said drawings similar letters designate corresponding parts in all of the several views, referring to Which- A indicates the frame or support ot my improved motor. In the preferred form of my invention this main frame or support in 'the form of `a float is provided with a bottom a, which extends its full length and width, the side Walls @which also extend its full length, and the inner longitudinal Walls c, which also extend the full length of the iioa-t and serve, in conjunction with the bottom o. and with an auxiliary bottom hereinafter described, to form the longitudinal central channel B, the purpose of which will be presently described. The longitudinal Walls l) c are connected at their ends by transverse Walls d, and they serve, in conjunction with said Walls d, the bottom a, and the top Walls c, to form. the longitudinal compartments C. Better illustrated in Fig. 3 of the drawings.) These longitudinal compartments C are divided by the vertical transverse partitions f into the several subcompartments C', and the said partitions f are provided adj acentn to theirlower ends with openings g, (see Fig. L) controlled by vertically-slidable valve-gates 7i, having handles i, whereby it will be seen that communication may be readily effected between the middle subcompartments C' and the subcompartments on opposite sides of the same when desired, for a purpose presently described.

Formed in the outer side Walls of the middle subcompartments C, as better shown in Fig. 3, are openings for the entrance of Water from the stream. These openingsj, like the openings g, are controlled by verticallymovable valve-gates lr., having handles Z extending to the top of the iioat, whereby it will be readily seen that the 'Water may be readily admitted into the middle subcompartments C from the stream, and as readily excluded therefrom when desired. From the middle subcompartments C' Water may be readily admitted to the subcompartments on opposite sides of the same by simply opening the gates 71., and in this Way the entire float- A may be submerged, or when desired for any reason TOO one end only maybe submerged, it being simply necessary when the entire iioat is to be submerged to open the gates 7c and all of the gates h, and when but one end is to be submerged to open the gates k and the gates 7L, opening into the subcompartments at the end to be submerged. In this way it will be observed that the float may be quickly and easily submerged without effort on the part of the operator or attendant,which is a desideratum.

In order to discharge the compartments C of the water therein when it is desired to raise the float, Iprovide in the middle subcompartments C the 'vertical pump or water-elevatorcylinders D, which eXtend from a point adjacent to the bottom a up to and through the top walls e,'so as enable them to discharge into the gutters m, which are formed in or on said top Walls e and lead to the outer sides of the boatso as to discharge the water back into the stream. I also provide the rotary water elevators or pumps E, which are arranged at the lower ends of the cylinders D and are fixed on the vertical shafts F, which are journaled in suitable bearings in the cylinders, as shown, 4and are designed to be lu-v bricated through the medium of the olle-ups n, arranged at the top of the float and connected by tubes p to the lower bearing of the shaft F, as illustrated.

The rotary pumps or elevators, one of which is illustrated in detail in Figs. 5 to 9, are similar in construction, and therefore a description of the one shown in detail will suffice for both. This pump or water-elevator E may be of any construction suitable to the purposes of my invention, but I, prefer to construct it as shown in Figs. 5 to 9. As thus constructed the pump or waterelevator E comprises the main frame or body q, having the central solid portion rdesigned to receive the shaft F, the bars t, which are preferably formedintegral with and extend radially from the central portion r, the ring t at the outer ends of the bars t, the circular ring r', which is connected to and extends upwardly from the edge of the solid portion r, and the ring s, which is connected to and extends upwardly from the ring t', the bars u, which are inclined in the direction of their width and have their ends arranged in correspondingly-inclined openings in the rings r' and s, and lthe inclined scoops or spoons c, which are arranged and secured upon the bars u and t, and are curved in the direction of their length to conform to the periphery of the body or main frame (Las illustrated. These scoops or spoons c are provided on their outer edges at their forward ends with the outwardly and upwardly extending and preferably integral flanges fw, which extend beyond the periphery of the frame or body portion and are designed and adapted to draw water into the path of the scoops or spoons, so as to enable said scoops or spoons to scoopit up when the elevators or pumps are rotated.

The rotary pumps or water-elevators are designed to be rotated from the driveshaft of the motor through the medium of mechanism hereinafter described, and when so rotated they will rapidly take up the Water from the compartments C and raise the same to the upper ends of the cylinders D, from whence it will be discharged through the gutters m back into the stream. will be observed, the compartments C may vbe quickly and easily discharged of water,

and the iioat raised, so as to permit of the motor being moved from one point to another, or for any other purpose.

Arranged in the longitudinal central channel of the float A above the bottom a thereof, and connected to the inner vertical walls c of the compartments C, isv the concave bottom G of the channel B. This bottom G extends the full length of the float A, as shown. and the space between the said bottom G and the bottom a is closed at the forward and rear ends of the float, so that the water will take through the channel above the bottom G.

I-I indicates standards in the channel B. which rise from the bottom G, and are pref erably of angular form in crosssection, as shown, so as to offer but a minimum amount of obstruction to the passage of the water. I indicates the shaft of the screw-wheel J which is journaled in the said standards H. and K indicates the blades of the said screw- Wheel, of which there are preferably four employed, as shown. These blades K extend spirally around or partly around the shaft I and conform to the curvature of the bottom G of the channel, whereby it will be seen that the current rushing through the channel will eXert a pressure against said blades, and will consequently forcibly and rapidly rotate the screw-Wheel. The shaft I of the screw-wheel .I is provided at its rear end with a sprocket-wheel a', and the drive-shaft L, journaled in bearings above the float, is also provided at its rear end with a sprocketwheel b', the twowheels being connected, as illustrated, by a sprocket-chain c', which is designed and adapted to transmit motion from the shaft I of the screw-wheel to the shaft L. The sprocket-wheels a b are lixedly connected to the ends of the shafts by screw-bolts CZ, which take through the wheels and into the shafts, and the connection of the said wheels to the shafts is further strengthened by the bolts c', which rest in grooves in the shafts and extend through the wheels and have their heads arranged in notches in the shaft and are secured in position in the grooves and notches of the shaft by collars f', which surround them, as shown. In this manner the sprocket-wheels are strongly and securely`connected to the shaft, and yet may be readily removed when necessary.

IWI indicates suitable supports which are connected to and rise from the compartments C and bridge the channel B, and N indicates the bearings in which the shaft L is jour- In this way, it

IIO

naled. These bearings N are arranged above the supports M and are adjustablysupported upon the same by the screws P, which take through threaded bearings in the top bars of the supports l\I and have their upper ends connected in a swiveled manner to the bearings, so as to permit of their being turned to raise or lower the said bearings. lVhen the bearings N are raised, it will be observed that the shaft L will also be raised and all slack in the sprocket-chain c will be taken up.

The shaft L is preferably provided with a balance-wheel Q, and at its forward end it has a beveled gear-wheel h', which is preferably connected in the same manner as the wheels a' b', and is designed for the engagement of the beveled pinion t" upon the upper end of the sha-ft R. This shaft R is journaled in a swiveled manner at its lower end in a support S, and extends through a slot in the upper bar of the support and has its upper portion jour naled in a lever T, fulcrumed upon the support, as better shown in Fig. 3, whereby it will be seen that its pinion 'i' may be moved into and out of mesh with the gear-Wheel h on shaft Il, for a purpose presently described. Adjacent to its lower end the shaft R is provided with a pulley T', which is preferably provided with two peripheral grooves to receive the belts U, which also take around pulleys V upon the upper end of the pump-shafts F, whereby it will be seen that when the shaft R is moved to carry the pinion c" into mesh with the gear-wheel 7L' the shafts F will be rotated and the pumps actuated by the motor, while when the shaft R is moved by the lever T to carry the pinion t" out of mesh with gear-wheel h the pumps, and consequently the removal of the water from the compartments C, will be stopped. The pumps may also, when desired, be actuated by hand through the medium of hand-Wheels or other suitable devices (not illustrated) placed on the shafts F..

Rising from the upstream end of the floatbottor'n u., which is extended beyond the compartments C and braced at its upper end by the braces WV, which are connected to the compartments C, is an upright X, which is of an angular form in cross-section, so as to offer but a minimum amount of obstruction to the passage of the water, and is shouldered, as indicated by u', for a purpose presently described, and connected in a hinged manner to the forward or upstream ends of the compartments C are the gates Y, which are designed and adapted 'when opened to guide a large volume of water into the channel B, and when closed to exclude the water from said channel, so as to prevent it from rotating the screw-wheel and actuating the motor. The said gates Y rest, when closed, against the shoulders of the upright X, and they may be opened and closed through the medium of any suitable mechanism. I prefer, however, to effect such movements of the gates through the medium of the Winches Z, which are mounted upon the compartments C and the cables Z', which are wound around the Winches and connected at opposite ends to the gates and take around sheaves on the braces W and post- X, as shown. lVith this construction it will be observed that when the Winches are rot-ated in one direction the gates will be opened, and when rotated in the opposite direction the gates will be closed, and it will also be observed that by locking the Winches against rotation, which may be done by any suitable means, the gates will be held in the position to which they have been adjusted.

In the practice of the invention the motor is secured against movement in a stream by stay ropes or cables connected to the banks of the stream or in any other suitable manner and when properly submerged in the manner described is ready for operation. In operating the motor the gates Y are opened sufliciently wide to aord a flaring entrance for the water. By reason of this it will be observed that a large volume of water will enter between the gates and will be guided thereby to the forward end of the channel B, which it will enter and traverse in a concentrated stream, and in consequence of this will exert great pressure against the blades of the screw-wheel and will forcibly and rapidly rotate the same. The rotation of the screw-` wheel is transmitted to the shaft L by mechanism before described, and from said shaft the power may be taken in any approved manner for driving various kinds of machinery. When it is` desired to stop the motor, it is simply necessary to close the gates Y, so as to exclude the current of water from the channel B, and when it is desired to raise the float of the motor to permit of it being moved from one point to another, it is simply necessary to place the pinion i in mesh with the gear-wheel h', when the pumps will be actuated in the manner before described.

In order to prevent the sprocket-chain c from obstructing the passage of the current from the downstream end of the channel B, I provide the V-shaped guards Z2, which are supported by brackets connected to the compartments C and are arranged in front of the said chain, as illustrated.

It will be observed from the foregoing that I have provided a hydraulic motor which, While cheap and durable, is capable of being operated without effort on the part of the attendant or attendants, and it will also be ob served that by reason of the construction of my improved motor the current of a stream may be concentrated so that it will rush through the channel B with great force and power and enable the motor to drive heavy machinery at a high rate of speed.

I have in some respects specifically described the construction and relative arrangement of the parts of my improved motor in order to impart a full, clear, and exact understanding of the same, but I do not desire to be understood as coniining myself t-o such IIO exact construction and arrangement, as such changes or modiiications may be made in practice as fairly fall Within the scope of my invention.
